Hey guys !! Here's a little writing post for tonight since i once again suffer from art block and i couldn't really get my thoughts on canvas so at least i'll write them down for you🥹🫶🏻

I had a little poetic moment about Cybertronians and how each bot from the Lost Light might view humans in their own way. Here’s how i think a few of them might feel, translated into their own brand of poetic musing:

Rodimus

"They’re like embers scattered on a night’s breeze. Small, insistent, daring to claim a spark of the vast unknown. Fragile? Yes, but isn’t fragility the very flame that burns the brightest in the dark?"

I think Rodimus sees in humans a little bit of reflection of himself—bold and driven, yet so often skimming along the edges of destruction. I think he would admire their recklessness despite their short lives and finds in them a kinship, like stars burning out as they fall.

Drift

"With hands of flesh, they reach for the stars, tiny pilgrims, undeterred by dark. They are warriors bound in tender shells, yet their spirits are sharper than any blade."

I think Drift sees humanity’s journey as sacred, an unlikely pilgrimage. Despite their fragility, they pursue wonders that many would fear, displaying a purity of heart that resonates with his own search for purpose and redemption.

Brainstorm

"They are puzzles, equations, broken in ways no theorem can solve. I could build them stronger, make them last longer, stretch their days to years—yet it’s the ticking clock that drives them which we cannot touch, the glitch of life within the code. They’re impossible, improbable—beautifully, infuriatingly unsolvable."

For Brainstorm, i think humans are the ultimate enigma. So imperfect, so baffling, so limited by their biology—and yet, somehow, they thrive. Their existence nags at him, like a problem he can’t quite crack, but one that has woven its way into his circuits.

Ultra Magnus

"They obey no Prime, no order, no code, yet they find honor in dust and devotion in ruin. There is chaos within them, yet in their eyes—clarity. For all their flaws, perhaps they see the law of the universe far better than we."

Ultra Magnus finds himself both exasperated and quietly moved by humans’ defiance of logic. I think he might struggle with their disorder but recognizes the strange beauty in their conviction. They possess a kind of honor that is beyond his ability to define—a law unto themselves.

Chromedome

"Stories woven in short threads of skin and sinew, their lives stitched in seconds, minutes, hours—a blink of a shutter. Yet they carry tales, so rich and raw, that I cannot forget. They are memory incarnate, fragile as newborn spark, but so full of color."

I think Chromedome would treasure humans for their stories, for the vibrant, bittersweet memories they create within the boundaries of their lives. Every moment for them is fleeting, and so they seem to capture life with a vibrancy he longs to archive.

Swerve

"They bumble and fumble, awkward yet bold, finding joy in the smallest things. They laugh in the face of a world so vast—their clumsy courage, a song I want to know by my spark."

We all know Swerve loves humans and human things. I think he sees humans as charmingly imperfect, stumbling yet fearless in a universe that dwarfs them. Their humor and resilience bring a joy that he can’t resist, as if they were a song that lingers in his circuits, warming him in ways he would never expected.

Megatron

"They are the dreamers, the fools, the ones who hope, rebels in skin who believe in the impossible. I have seen it. They build kingdoms on bones and dreams, believing they can change the world."

Megatron is an amazing character in my opinion in the Lost Light universe. I think he looks upon humanity with a blend of scorn and admiration. They are so weak, yet so defiant—champions of hope despite their powerlessness. Their resilience reminds him of what he once fought for, and though he might deny it, he can’t help but see in them a reflection of his own self.

Ratchet

"Flawed and failing, breaking with each breath, they stitch themselves back with their tender hands. They fall, they fail, yet rise again reminding me why I mend the wounded steel."

I really like Ratchet. I like to think he regards humans with a mix of exasperation and reluctant respect even when he wouldn't directly word it. He sees them as frail and imperfect, breaking down as quickly as they heal. Yet, their resilience, their refusal to give up despite everything, is what keeps him caring deep in his spark. In their struggles, he finds purpose, and in their imperfection, he rediscovers his own reason to heal.

I hope you liked this silly little post for tonight. I hope the art block goes away soon so i can draw more silly robots and their silly lil human friends together :3🧡🧡🧡

i am soooo sorry if you’ve already been asked this. however, do you have any ratiorine fics you’d recommended??? i haven’t been that intrigued by aventurine’s characterisation in a lot of the ones ive read and was wondering if there are any you have particularly enjoyed, as someone who understands him so well 👍 if not no worriesss

Someone else asked this earlier as well, and I started trying to put together a list of recs, but I struggled so badly because even though I leave kudos or comments, I virtually never remember to bookmark fics, so there's all these fics whose plots or writing I remember as being great, but... what were the titles... I always flounder to find fics again anytime I want to try to make a list of recommendations. (There's also the fact that even if I post a ton about analyzing characterization in canon, my standards for fanfics are... not that high. I'm definitely the "read whatever I see that day" type. 😂)

But here are just a few I could remember, and maybe I can come back and add more to the list later:

Ratiorine Fic Recs

Nagare's "deal with me" - An AU about wish-granting witches that captures the experience of Aventurine being cursed/blessed very well, in my opinion.

Chashmish's "On the Circumvention of Ethics" - I think this is probably exactly what Aventurine would do in canon, post-Penacony.

JMGAngel's "Friendship and Other Related Disasters" - The ratiorine is actually just background in this one, but since you mentioned Aventurine, I really appreciated this fic taking time to include interactions between Aventurine and other characters which I haven't seen much (if ever) in other fics.

vahveroinen's "Open Circuits" - I was a big fan of the "Rota Fortunae" short, so a RF AU fic is also a treat. After this, I feel like a lot of the Ratiorine fics I enjoyed are already really popular, so I'm not sure I need to recommend them even, but I did also enjoy these:

Irisinally's "Of broken nightmares and rotten memories" - A very cool AU scenario with interesting world-building.

katraa's "fermat's last theorem" - Even if you see the plot twist coming, it's a great reveal.

profligate's "a dissertation on affection as a logical locus, by Dr. Veritas Ratio, Ph.D." - Another interesting AU, and I appreciate that the author allowed Aventurine to both do his job and do something good.

greenery_0's "the appeal of domesticity" - For when you want something really light-hearted and cute. To finish off this post, I also want to take the time to plug two Ratiorine fics that were inspired by Ratiorine posts I made! Please go send these guys some love for taking their time to write things inspired by my silly Ratiorine ramblings!

Thetinir's "Apex predator" - AU playing on Ratio and Aventurine's alien biology.

Suidice's "Work-life Imbalance" - Internal IPC messages tracking the evolution of Ratio and Aventurine's partnership.

In the last post I said:

Gödel's second incompleteness theorem says in particular that a system at least as powerful as PA which proves its own consistency is inconsistent.

Writing this sentence makes me wish humans could handle center-embedding. This sentence is a horrible garden path if you're unfamiliar with the topic, as often occurs when trying to talk about math (because of all the restrictive relative clauses, representing the various conditions to theorems). Syntactic ambiguities often pile up too. Cutting out some unnecessary adjunct phrases, we have:

Gödel's second incompleteness theorem says that [ [ a system which proves its own consistency ] is inconsistent ].

vs.

Gödel's second incompleteness theorem says that [ a system [ which proves its own consistency is inconsistent ] ].

The latter of course being ungrammatical, but a tempting initial reading.

If we had head-final CPs with head-initial NPs (or conversely head initial CPs with head-final NPs), there would be no problem. Cf.

Gödel's second incompleteness theorem says that [ [ a system proves its own consistency which ] is inconsistent ]

for the first reading, vs.

Gödel's second incompleteness theorem says that [ a system [ proves its own consistency is inconsistent which ] ]

for the (ungrammatical) second reading. Ignore "that" still being in a head-initial position, it's not relevant for the point I'm making. Anyway, unfortunately, even if English worked this way—as, you know, Sumerian maybe sort of did with its case particles, and whatnot—we still wouldn't be able to phrase complex unambiguous mathematical expressions with it, because the human speech processing doohickey hates this kind of center-embedded structure at embedding depth greater than 2. Uh, for instance we can say:

The dog the cat saw

And we can say:

The dog the cat the mouse feared saw

And it's already starting to get difficult to process, and then if we try to say:

The dog the cat the mouse the chicken pecked feared saw

It's basically unparsable, even though it's nominally grammatical. Compare the relatively unproblematic right-embedded paraphrase:

The dog who was seen by the cat who was feared by the mouse who was pecked by the chicken.

Well, if English had head-final CPs, you'd have:

The dog the cat saw which

Ok,

The dog the cat the mouse feared which saw which

Doable,

The dog the cat the mouse the chicken pecked which feared which saw which

Horrendous. At best, an attempted paraphrase gets you:

The dog was seen by the cat was feared by the mouse was pecked by the chicken which which which

Which is I guess parsable, but I suspect you will not consistently get the right number of "which"s. Which incidentally will also reintroduce syntactic ambiguity.

So, ok, I don't actually know for sure if native speakers of this hypothetical language would have trouble with these constructions. But it's telling that everybody in every language seems to avoid center-embedding, in Japanese you get the reverse sort of center-embedding when relativizing on objects and, I have to dig up the paper, but I'm pretty sure speakers use paraphrase to avoid doing that more than once. And obviously, my pet example, in Sumerian you have the NP structure Noun-Genitive-[Case Clitic], and you apparently almost never see the genitive clitic =ak more then two or three times in a row (I suspect it depends on the complexity of the embedded phrases).

So, we're fucked. We're fucked if we want unambiguous parsing, we're fucked if we ever want to talk about theorems in a way that is both clear and non-circuitous in a single sentence.

Well it's probably fine. Mathematicians are getting along fine. None of this is a real problem.

The Quantum Arrow of Time: Insights from Superconducting Circuits

Quantum mechanics, at its core, is governed by equations that are time-symmetric. This means that if you were to reverse the direction of time in these equations, they would still hold true. For example, Schrödinger's equation, which describes how quantum states evolve over time, is symmetric with respect to time reversal. This symmetry implies that, theoretically, any quantum process could occur in reverse. However, the act of measurement introduces a crucial asymmetry. When a quantum system is measured, it collapses into one of its possible states, a process known as wave function collapse. This collapse is inherently probabilistic and introduces an element of irreversibility. Once a measurement is made, the system cannot spontaneously revert to its prior superposition of states—this is where the arrow of time becomes evident.

The statistical arrow of time emerges from the likelihoods associated with forward and backward processes. In experiments involving quantum systems like superconducting circuits or ultracold atoms, researchers can capture sequences of quantum states—akin to making "movies" of quantum behavior. By analyzing these sequences, scientists can determine the probability of observing a particular sequence in forward versus reverse order. Fluctuation theorems provide a quantitative framework for understanding irreversibility in quantum systems. They relate the probabilities of forward and backward processes and show that while individual events might appear reversible, the overall statistical distribution favors a forward direction. This statistical bias is what gives rise to the arrow of time in quantum measurements.

Irreversibility in quantum measurements is closely tied to information dynamics. When a measurement is performed, information about the system's state is extracted and recorded. This extraction process increases entropy and creates an irreversible change. The strength of the measurement correlates with the degree of irreversibility: stronger measurements lead to more definitive state collapses and greater irreversibility. In some experiments, it has been shown that the arrow of time in quantum systems is more closely related to information exchange than energy dissipation. This suggests a fundamental link between information theory and thermodynamics at the quantum level.

These insights into quantum measurement and the arrow of time have profound implications for our understanding of time itself. They suggest that while at a fundamental level, physical laws do not distinguish between past and future, the act of measurement—and by extension observation—imposes a directionality on time.

[exnihilo-comic]

what math subject it’s your favorite? (like geometry, arithmetic, algebra etc)

i really like algebra, and after that, arithmetic at a close second. algebra i was actually really bad at in school, i had to take pre algebra twice. in fact my life would be very different today if i didnt due to the confluence of forces surrounding that fact.

i want to make a comic about when i kind of knew that i loved mathematics so much, and part of that is how arithmetic and algebra have so many patterns that fit together. the way whole numbers are connected with one another and form relationships fascinated me so much.

beyond those i do like geometry but im rubbish at construction and forming proofs and remembering theorems. i REALLY enjoy graph theory bc of the way it can create this unique world of rules on the 2D plane. i would draw k-graphs when i was bored and look at euler paths and circuits and play my own little königsberg bridge games as a child

Min vs SP24

I'm excited about my classes this semester, so why not talk about them here. (I'm procrastinating an email I have to reply to and a bunch of job stuff I need to set up)

Intermediate Quantum Mechanics

I didn’t do so hot on my first quantum class so I’m glad for the do over. I’m appreciating the heavy emphasis on mathematical formalism this time

Particle Physics

Ooooooh I’m most excited about this one. It’s supposed to be an undergraduate level introduction to the topic. I hope it will build some intuition around the QFT I’ve been studying on my own. 

Matrix Groups

I fell in LOVE with algebra last semester and I’m really curious about Lie algebras so I hope this class will FINALLY tell me more about Noether’s theorem. 

Circuits

I’m only taking this class because I have to. 

Data Analysis and Research Techniques in Astronomy

I forgot I was on the waitlist for this one lmao. I’ll check it out but I’ll probably drop it anyway to focus on research.

and then research + TAing as usual. Hopefully, I get to TA the Lagrangian mechanics class because it's my favourite physics class here so far.

Here's to building better study habits this semester!

[frompoemsthativeread]

Today, the average high school student has the same anxiety levels as the average 1950s psychiatric patient. We know the Pythagorean theorem by heart, but short-circuit when anyone asks us, How are you? We don’t know. We don’t know. That wasn’t on the study guide.

We usually know the answer, but rarely know ourselves.

Autism and Decisiveness

Pretty quickly, today's algorithm decided to put two posts about decision-making and autism in front of me, so here we go with that.

First, the two posts. One was a TikTok from @ morgaanfoley which I tangent'ed off with the very first example on "favorites"...

The second was a post compiling some responses to a tweet from @ BurleyMariah:

View on Twitter

Anyway, I've written about these things before in different contexts, so I'll post here to combine some points... Also, the following post got super long, so I'll put the TLDR up top:

Autism (and some other neurodivergencies) and Decision-Making

The slightest increase of selection-criteria and number of choices results in making it impossible to have a "best choice". This is a mathematical fact, thus true for any neurotype (though more likely to be ignored by allistics).

Neurodivergent memory (lethomathica) and monotropism means we are more likely to lack context we would want to have for decisions.

Neurodivergent persons are more likely punished by others for decisions they make (and have a history of being punished for decisions made in the past whenever they have not provided a choice acceptable to others). (With autism and trauma, this tends to lead to seeking the "best choice" because "surely they cannot argue with the best possible choice that is clearly the best" but (1) means there is rarely a best choice and never a consistent method of picking that best choice and (2) means we regularly overlook context and information we do not have access to and this ignores the fact that many frequently do have an issue with a choice even if it is better in every relevant way).

The answers people look for to questions (even seemingly simple ones) are not the literal answers to the questions but instead what they think the answer to the question means. This is true even for autistic questioners and answerers (especially any who mask) but reaches absurd levels of "subtext" when done by allistic individuals.

First!

There is a very relevant fact that I'll try to spare you from the intricacies of but it applies regardless of neurotype: Even if you are ranking objective qualities, if there are more than two things to rank, it is impossible to have a consistent "best choice" unless one quality is the only one that matters or one thing wins every quality.

(This is a consequence of something called "Arrow's Impossibility Theorem" which you hopefully would learn about in a math or social studies units on election systems. More specifically, Arrow's states that there's no best method to make a choice, not that it's impossible a specific choice isn't the best choice in a particular instance).

Fun autistic tie-in: monotropism allows a lot of autistic people to actually have consistent "best choices" (best choice for us), presumably because there is a narrower range of qualities which are more important to us when judging a selection. This can help explain some of our sensibilities regarding autistic same foods and our common immersion into fandoms or rewatching or repeating similar experiences.

Second!

Neurodivergent memory is a thing. I refer to all neurodivergent memory under the umbrella of "lethomathica" (modeled after tip-of-the-tongue syndrome, "lethologica" but replacing words—"logica"—with knowledge—"mathica").

Although I developed the term lethomathica to refer to what I saw more as an AuDHD/ADHD thing, it wasn't long before I realized that PTSD and autism had their own memory issues that were pretty related. Namely, extremely vivid memories whose access is not always in control of the person with the memories.

Monotropism can partially explain the accuracy and detail of the memories for both autistic persons and trauma survivors (we know that knowledge circuits get reinforced with "deep learning" and both monotropism and trauma is "deep learning" on demand). The access to those circuits might be narrowly defined though. Sure, it's as deep as the ocean once you get to them, but you have to go through a wilderness trail to get to the shore in the first place.

Borrowing the language of PTSD, the "trigger" to access a knowledge circuit, the connection from everyday memories to the specific knowledge needed, isn't what was reinforced. The knowledge circuit is what was reinforced, so even if you are able to recall literally every detail of an event or topic or specific knowledge once you have access, the access may be hidden or obscured.

(I should mention, the relation between learning and trauma are my own theories. The theories on learning come from reading, research, and my experience as an educator, but connecting the theories on learning to trauma comes from me. I don't see how they aren't related looking at what we know about learning and what we know about trauma, but I've had people complain and I want to be clear where things come from. As with all information about neurotypes and mental health, if something is useful for your life, then I encourage you to use it, and if it isn't useful, then I encourage you to move to something that is useful. The important thing is your health and wellbeing.)

As an example, I recently rediscovered The Real Adventures of Jonny Quest via an offhand reference to shadow puppets, this then led to me not only re-remembering things like my crush on the character of Jessie Bannon and re-remembering specific episodes that made an impression on me, but also re-remembering more Toonami shows I had forgotten (or shows I associate with Toonami) like the show, ReBoot. Now, I maintain a pretty OK connection to Toonami shows in my brain, but this connection is primarily to anime like Dragon Ball Z and Cowboy Bebop. I needed the additional context of American-produced shows and bad (by modern standards) CGI to go down the rabbit hole of ReBoot.

Aside: Reading about the reaction of classic–Jonny Quest fans to the character of Jessie Bannon (spoiler: she's ostensibly a girl) in 1996 really gave me déjà vu to Star Wars reboot with Rey. Or I guess, déjà rêvé? Since the timing is backwards?

Additional aside: any other autistic persons used to experience déjà rêvé to the point they thought they had prophetic dreams? …There's a reason why autism is related to chuunibyou, but that's a different post.

None of these are my "favorite" animated show—though Real Adventures probably was at the time it aired for child-Me and Cowboy Bebop would rank high on any complete list of favorites even for present-Me—but both give me context into who I am as a "fan". Jonny Quest perfectly set me up for monster-of-the-week shows like Doctor Who and Supernatural and Cowboy Bebop is just a masterpiece that I'd be extremely disappointed to find out I excluded from a favorites list even if it wouldn't take the top spot (or maybe it would? I'm not going to do the analysis when I know that Arrow's is there to tell me there's no reliable way to select my favorite along with years of trying to rank things only to find out that my opinion was different from past-Me's opinion and I almost certainly would forget a show I shouldn't and wouldn't want to forget). Cowboy Bebop would have set me up to more enjoy Firefly if that particular IP wasn't so transient and ephemeral and did set me up to enjoy Serenity even without Firefly.

This restriction of available context—having relevant knowledge that could help us make better decisions—contributes to us encountering many scenarios where we make a decision and then get punished for that decision. These scenarios are all the more tragic because the relevant information was in our heads somewhere, we just didn't access it in time.

…end of example.

Third!

CPTSD (Complex PTSD), the neurodivergent accompaniment—though maybe obbligato is more accurate—colors our decision making in ways we commonly overlook. When I talk about being "punished" for a decision, sometimes I mean in the sense that we didn't make the ideal choice, but, all too frequently, we are literally punished for our choices. Maybe it's us being mocked or ostracized, or maybe it's outright rejection or denial of our choice. In those cases, hesitating to make a choice might be the safest choice of them all.

Any marginalized population gets repeatedly undermined merely as a function of living within a larger population. The popular ADHD number batted about is that by the age of 12, an ADHDer will receive 20,000 additional negative comments about themselves than a non-ADHDer will.

Based on that estimate, if a non-ADHDer receives one negative comment a day, an ADHDer receives six negative comments a day. How many of those are about decisions the ADHDer made where they were not expecting pushback?

(There are about 4,000 days a twelve-year-old has lived; 20 thousand additional negative comments / 4 thousand days = 5 additional negative comments per day).

If you give us a punishment when we do make a decision, that makes it that much more difficult to make a decision the next time. The question may be "What's your favorite movie?" but there are "safe" answers that we can get caught up trying to anticipate and provide. People like to say "honesty is the best policy" but, like most things allistic people say, that tends to just be lip service… but sometimes it's not lip service and either way they're going to make up their minds about who we are as a person regardless of the "truth" or accuracy of their judgements even when viewed from their own perspectives. Then they'll just get mad at us for presenting the way we did when it led them to believing something that wasn't true even if what we presented was truth and they interpreted it as lies.

I'm getting a little long-winded, so let's call it with the next one:

Fourth! Lastly! Everything must go? Questions are onions? Kind of?

Questions have layers. Even between autistic questioners, very rarely is the question simply, "What do you want to eat?"

Food has baggage, not just nutrition and taste—though both of those are relevant—but the baggage of prep, cost, time, and more. I may want to eat pizza or I may want to eat macaroni and cheese, but both of those are likely to make me sick in any substantial quantity so I definitely cannot have one for lunch and the other for dinner. Then there's the question of do we have clean dishes? Do we have ingredients? Do we need to brave the grocery store or a crowded restaurant? How consistent is the restaurant and what factors affect their consistency? Do they know what "extra hot" means or do they judge how hot my latte is by vibes alone? How nice are the people I have to navigate? Are there robot clerks? How accessible is everything? How noisy is everything? What sort of looks will I get if I go there? How safe is it? How likely am I to be pulled over by a police person for my existence on the way?

"Would you rather go to a party or a library?" Trick question punishment game! Library means you're autistic even if the last party you went to was at a bookshop and had fluffy, friendly cats to pet or the last library you went to was a raucous, sensory nightmare where no one followed the rules but somehow you still got people tsk'ing you and complaining.

Even less obvious trick questions result in punishing desirable qualities. "Gullible"? Oh, you meant "trusting one's friends"?

"Are you ticklish?" typically means, "I'm going to put my hands on you now no matter whether you reveal a 'weakness' or you claim otherwise."

So yeah.

Thanks for reading! I post my more off-the-cuff things I have to say here on Tumblr (since the last primarily-text-based social media site I enjoyed died) but follow me other places in case this particular site goes further down the tubes. Here's all of my sites probably:

The Building Blocks of Electrical Engineering: What Every Student Should Master

A solid grounding in the fundamentals is essential for every aspiring electrical engineer. Mastery of these core concepts not only enables effective problem-solving and innovation but also forms the basis for all advanced studies and professional success in the field.

Core Principles and Laws

Ohm’s Law: This fundamental law relates voltage, current, and resistance in a circuit. It states that the voltage across a conductor is directly proportional to the current flowing through it, provided the physical conditions remain constant (V = I × R).

Kirchhoff’s Laws:

Kirchhoff’s Current Law (KCL): The total current entering a junction equals the total current leaving it.

Kirchhoff’s Voltage Law (KVL): The algebraic sum of all voltages around any closed loop in a circuit is zero.

Network Theorems: Thevenin’s and Norton’s theorems are essential for simplifying complex circuits and analyzing their behavior.

Basic Electrical Quantities

Current (I): The flow of electric charge, measured in amperes. It is the movement of electrons through a conductor.

Voltage (V): The electrical potential difference that drives current through a circuit, measured in volts.

Resistance (R): The opposition to current flow, measured in ohms. It depends on the material, length, and cross-sectional area of the conductor.

Power (P): The rate of energy transfer in a circuit, calculated as P=IVP=IV, measured in watts.

Circuit Elements and Analysis

Passive Elements: Resistors, capacitors, and inductors, which absorb or store energy but do not generate it.

Active Elements: Voltage and current sources that supply energy to the circuit.

Series and Parallel Circuits: Understanding how components behave in series (same current, voltage divides) and parallel (same voltage, current divides) is crucial for circuit analysis.

Star-Delta Transformation: A technique for simplifying complex resistor networks.

Types of Circuits

DC Circuits: Circuits powered by a constant direct current source. Analysis involves the steady-state behavior of resistors, capacitors, and inductors.

AC Circuits: Circuits powered by alternating current sources. Analysis includes understanding reactance, impedance, and phase relationships.

Single-phase and Three-phase Systems: Essential for understanding power distribution and the operation of industrial equipment.

Electromagnetism and Machines
